yeah, they are rear fanged with "mild" venom. they are Ahaetulla Prasnia... one is not, i still cant figure out what it is. its not ahaetulla prasnia, nasuta, mycterizans which are the most common. it looks to me like an ahaetulla fasciolata but, their is only one place in the world that has them in captivity.... maybe a hybred of prasnia x mycterizans? i will post pics if you want to see him.
